Title: Dc motor and controlling method therefor
Inventor: MOROTO KIYONORI
IPC: H02P7/29
Filed: 2001-03-19
Abstract: PROBLEM TO BE SOLVED: To extend the service life of a motor by reducing rectified voltage for restraining arc discharge generation, or, to reduce electromagnetic noise. SOLUTION: Six coils 7 are connected to each segment 8a in which one end thereof constitutes a rectifier 8, and the other end of each coil is connected to neutral positions n1 and n2. In two pairs of brushes 4, a plus-side brush 4 of one pair is short-circuited with a minus-side brush 4 of the other pair. This makes it possible for a primary coil group and a secondary coil group to be energized in series with each other through the two pairs of brushes 4. With this constitution, the voltage at one phase of coils 7 is decreased by a half of that in a conventional type, which also reduces the voltage when rectified in a half. This would mean that even if the power voltage doubles, the voltage when rectified would not increase more than that in a conventional type.  As a result, arc discharge generated between the brushes 4 and the rectifiers 8 when rectified can be restrained, so that wear to the brushes 4 and the rectifiers 8 can be reduced. It is thus possible to extend the service life of the motor.
